A matrix printer usually stores the print data in memory in coded individual entities or blocks (e.g., characters in a text environment). A significant portion of that block's storage may be dedicated to data that is all white (binary zeros) (see the figure). Elimination of these all white areas in storage would result in increased storage without loss of information. This problem is important in storage of non-coded information (NCI) data also, if it is stored as described above.
